The present invention relates to an air cleaner, and more particularly, to an intake system to which an air cleaner suitable for a high-performance vehicle in which bolts or springs are removed while being a circular filter with a filter fixing structure using an adapter.

In general, the intake system of a vehicle is an air cleaner with a built-in round filter that filters out foreign substances contained in the outside air, and converts the outside air into clean fresh air and supplies it to the engine.

To this end, the air cleaner is implemented as a filter replacement type air cleaner that can replace a contaminated round filter with a new round filter by applying a bolt fixing method of a bolt fastening structure or a spring fixing method of a spring support structure.

For example, in the bolt fixing method, the circular filter accommodated in the air cleaner body is positioned on the bolted seat surface of the air cleaner body together with an adapter of a separate product, and then the circular filter is assembled by fastening the bolts. This is a method of separating the circular filter with For example, in the spring fixing method, the circular filter is assembled by the spring fastening of the spring coupled to the filter fixing part of the circular filter pushed into the air cleaner body with the air cleaner cover and the spring attachment part formed on the inside of the air cleaner body. It is a method of separating the circular filter by removing the cleaner cover and releasing the spring.

It is assembled to the cleaner (1). In this case, the filter assembly angle Kc is determined by lifting the front fixing flange 85 side of the filter 80 positioned as the filter flange 11A and lowering the rear fixing flange 87 side to the bottom of the filter 80. is assembled in an upwardly inclined arrangement. In addition, y-y denotes an imaginary filter axis connecting the center of the circular cross-section of the filter 80, and x-x denotes a imaginary horizontal line for y-y, respectively. And the front, back, up, down and left and right directions of the filter 80 are the filter adapter ( The side receiving the pressing force of 40) is in the rear direction, and when one side is turned to the left with respect to the center of the full length axis of the filter (80), the other side is to the right side, and the air cleaner cover (30) is applied to the cross section of the filter (80). ) is defined as a portion in contact with the air cleaner body 20 in an upward direction and a portion in contact with the air cleaner body 20 in a downward direction.

The filter fixer 20 has a constraint structure by the adapter guide member 21 for guiding the fitting path of the filter adapter 40 and the filter constraining members positioned in the front, back and left and right sides of the filter 80. Together with the left and right side surfaces of the frame 83, a filter binding force is formed for the front and rear fixing flanges 85 and 87. In this case, the filter constraining member includes a filter supporting member 22 , a filter mounting member 23 , a filter positioning member 24 , and a filter pressing member 25 . In addition, the filter adapter 40 is positioned on the rear fixing flange 87 of the filter 80 in a fitting structure to be inserted into the adapter guide member 21 having an acute angle adapter guide angle W. As shown in FIG. The filter adapter 40 is a filter 80 in a state in which a wedge-shaped adapter body 41 having an acute filter wedge angle Kb forms a right angle with the filter support angle Ka of the filter support member 22 . ) by pressing the rear fixing flange 87 of the filter fixing force.

In particular, the filter support angle Ka connects the filter support member 22 and the filter seating member 23 on the same line, and forms an obtuse angle with the filter support member 22 and the adapter guide member 21 while forming an obtuse angle with the filter adapter ( 40) and form a right angle. Therefore, the filter support angle Ka is the filter support member 22 supporting the rear fixing flange 87 of the filter 80 at a right angle while the filter seating member 23 is the front fixing flange 85 of the filter 80. By supporting the at right angles, the filter 80 assembled to the air cleaner 1 is stably maintained in a state inclined at the filter assembly angle Kc. In addition, the left and right side surfaces of the filter 80 are fixed by the filter binding force by the filter positioning member 24 being positioned on the left and right side surfaces of the filter frame 83 .

In addition, the adapter guide angle W serves to stably maintain the fitted state of the filter adapter 40 while facilitating the insertion and separation of the filter adapter 40 . And the filter wedge angle Kb acts to press the filter 80 between the adapter guide member 21 and the rear fixing flange 87 .

Referring to the perspective view in which the hose housing 10-1 and the duct housing 10-2 of FIG. 3 are fusion-bonded, the adapter guide member 21, the filter support member 22, and the filter mounting member 23 of FIG. , the detailed structure of the filter positioning member 24 is illustrated.

Specifically, the adapter guide member 21 protrudes upward from the bottom surface of the adapter guider 21A and the duct housing 10-2, which protrude laterally from the inner wall of the hose housing 10-1 to form an inclined surface. Since the adapter supporter 21B is formed, the adapter guider 21A and the adapter supporter 21B are spaced apart from each other. In addition, in the adapter guider 21A, a left insertion channel 21A-1 is formed as a left position of the inclined surface and a right insertion channel 21A-2 is formed as a right position of the inclined surface, respectively, and the left and right insertion channels 21A-1 are formed in the adapter guider 21A. , 21A-2) is coupled with the left and right insertion protrusions 45A and 45B (see FIG. 5) of the adapter body 41 to hold the insertion direction together with the insertion position of the filter adapter 40.

In particular, the imaginary inclined line connecting the inclined surfaces of the adapter guider 21A and the adapter supporter 21B forms the adapter guide angle W, so that the filter adapter 40 is connected to the adapter guider 21A of the hose housing 10-1. ) and acts to be positioned on the adapter supporter 21B of the duct housing 10-2. In particular, the inclined plane virtual line formed by the adapter guide angle W forms an insertion space at an adapter fitting angle with respect to the rear fixing flange 87 of the filter 80 supported at a right angle to the filter support member 22, The adapter fitting angle is slightly smaller than the filter wedge angle (Kb) so that a filter fixing force can be formed by pressing the adapter body 41 against the rear fixing flange 87 of the filter 80 when the filter adapter 40 is fitted. is formed

Therefore, the adapter guider 21A and the adapter supporter 21B guide the insertion path of the filter adapter 40 from the adapter guider 21A to the adapter supporter 21B with a virtual line forming the adapter guide angle W. By giving the filter adapter 40, it is easy to insert and remove the operation.

Specifically, the filter supporting member 22 supports the rear fixing flange 87 of the filter 80 at a right angle from the bottom surface of the duct housing 10-2, and at the same time, the filter mounting member 23 is connected to the duct housing 10 -2) protruding from the inner wall of the inner wall to support the front fixing flange 85 of the filter 80 at a right angle so that the filter 80 is tilted at the filter assembly angle Kc and assembled to the air cleaner 1 keeps it stable in In particular, the filter support member 22 is formed at an intermediate position in the width of the duct housing 10-2, and has a horizontal shape with respect to the vertical adapter supporter 21B to form the filter support angle Ka as an obtuse angle. The adapter supporter 21B and the bottom surface of the duct housing 10-2 are integrally formed. In addition, the filter seating member 23 is formed by extending the inner rib 15 formed on the inner wall of the duct housing 10-2 from the lower position of the filter flange 11A of the hose housing 10-1, and in particular, mutually By being formed in a plurality of arrays spaced apart, it acts to increase the dynamic rigidity of the duct housing 10 - 2 together with the maintenance of the support state of the front fixing flange 85 necessary for the maintenance of the filter 80 .

Therefore, the filter support member 22 and the filter seating member 23 form the same line with the filter support angle Ka as an imaginary line, and the imaginary line is the filter imaginary axis yy of the filter 80 . parallel to

Specifically, the filter positioning member 24 includes left and right filter holders 24A and 24B protruding to face each other from the left and right inner walls of the duct housing 10-2, and the left and right filter holders 24A and 24B. Each of 24A and 24B restrains the left and right sides of the filter frame 83 of the filter 80 supported by the filter supporting member 22 and the filter mounting member 23 to prevent the left and right tilting of the filter 80 works to do

Referring to the perspective view of the air cleaner cover 30 of FIG. 4 , the filter pressing member 25 is formed on the front and rear longitudinal inner walls of the air cleaner cover 30 . In this case, the front longitudinal direction of the air cleaner cover 30 among the front and rear longitudinal directions is defined as a portion where the hose outlet contact surface 31 is formed in close contact with the hose outlet 11 of the hose housing 10-1.

In particular, the filter pressing member 25 protrudes from the front inner wall at a position facing the adapter pusher 25A and the adapter pusher 25A protruding from the rear inner wall of the air cleaner cover 30 . It consists of a filter pusher (25B). As a result, the filter adapter 40 is pressed by the adapter pusher 25A, and the front fixing flange 85 portion of the filter 80 is pressed by the filter pusher 25B. Therefore, the filter pressing member 25 causes the filter adapter 40 to fall out from disturbance due to the action of the air cleaner cover 30 pressing the air cleaner body 20 when the cover clamp 60 is locked and the filter 80 . block the shaking shape of

Referring to the perspective view of the filter adapter 40 of FIG. 5 , the filter adapter 40 includes an adapter body 41 , a filter fixing rib 43 , left and right insertion protrusions 45A and 45B and a rigid rib 47 . is made of

Specifically, the adapter body 41 has a wedge-shaped wide end as an upper end 41A and a narrow end as a lower end 41B, and the upper end 41A and the lower end 41B surround the bottom surface and protrude. By forming the outer edge, the filter wedge angle Kb of an acute angle is formed by the difference in thickness between the lower end 41B and the upper end 41A. Therefore, the bottom surface of the adapter body 41 is divided into an inner bottom surface in which the lower end 41B and the upper end 41A form an outer edge, and an outer bottom surface in which the outer edge is not formed.

Specifically, the filter fixing rib 43 protrudes in an arc shape of a predetermined thickness at a distance from the upper end 41A from the inner bottom surface to contact the rear fixing flange 87 of the filter 80 . Therefore, the filter fixing rib 43 prevents the filter 80 from falling out in the upward direction (that is, toward the air cleaner cover 30) due to the repulsive force caused by the filter wedge angle Kb in the process in which the filter adapter 40 is fitted. works to block the phenomenon. The left and right insertion protrusions 45A and 45B are formed to have a predetermined thickness at intervals in the longitudinal direction on the outer bottom surface of the adapter body 41, and the left and right insertion channels 21A-1 and 21A of the adapter guider 21A -2), thereby constraining the position of the adapter body 41 when the filter adapter 40 is inserted and removed. A plurality of rigid ribs 47 are formed on the inner bottom surface of the adapter body 41 at intervals in the longitudinal direction to a predetermined thickness to enhance the rigidity of the adapter body 41, thereby increasing the dynamic rigidity of the filter adapter 40. works to

Referring to FIG. 6 , when the air cleaner 1 is assembled, the upper surface of the air cleaner pressed Fa and the intake filter Fb received by the filter 80 are exemplified.

Specifically, when the air cleaner body 20 and the air cleaner cover 30 are combined, the air cleaner cover 30 presses the air cleaner body 20 when the cover clamp 60 is locked. and the adapter pusher 25A is formed by pressing the upper end 41A of the adapter body 41 by pressing the air cleaner cover 30 . As a result, the upper surface pressing Fa of the air cleaner strongly restrains the filter adapter 40 to prevent the filter adapter 40 from being pulled out from the disturbance applied to the air cleaner 1 .

Specifically, when the intake filter is pressed (Fb), the adapter body 41 is inserted into the insertion space of the adapter fitting angle, and the filter fixing rib 43 is in contact with the rear fixing flange 87 of the filter 80. When the body 41 is pushed in, the filter fixing rib 43 is formed by continuously pressing the rear fixing flange 87 . As a result, the intake filter press Fb strongly restrains the filter adapter 40, thereby strengthening the prevention of the filter adapter 40 from being pulled out.

In particular, the rear fixing flange 87 of the filter 80 is connected by hooking the lower end 41B of the adapter body 41 to an arc-shaped glove 89 dug into the rear fixing flange 87, thereby connecting the filter adapter. (40) to further strengthen the prevention of the drop-out phenomenon.

The airtight structure of the air cleaner 1 of FIG. 7 shows an example using the housing strap 50 and the filter strap 70 .

Specifically, referring to the airtight structure of the housing strap 50, the hose housing 10-1 has a strap channel 12a-1 in which a plurality of strap protrusions 12a-2 are formed on the strap flange 12a at predetermined intervals. ) to form Therefore, the housing strap 50 having a predetermined thickness has a strap channel 32a-1 (Fig. 4), and it is seated by inserting it into the As a result, the housing strap 50 seals the strap flanges 12a and 32a while being inserted into the strap channels 12a-1 and 32a-1 to form an airtight seal to the internal space. In particular, since the strap protrusion 12a - 2 is formed as an arrow-shaped fixing protrusion, the binding force to the housing strap 50 can be strengthened.

Specifically, referring to the airtight structure of the filter strap 70, the hose housing 10-1 has a double groove structure of the filter flange 11A, and the close contact flange 85A of the filter 80 and the filter strap 70 By inserting the filter 80, it connects to the hose outlet 11 side. As a result, the filter strap 70 encloses the outer diameter of the close contact flange 85A while being fitted into the double groove of the filter flange 11A, thereby forming an airtightness to the filter 80 .

To this end, the filter strap 70 includes an annular contact body 71 , an insertion flange 73 protruding from one side of the contact body 71 , and a fitting protrusion protruding to a predetermined thickness from the outer diameter of the contact body 71 . (75).
